Exact-match DDR5-6400 kit for Supermicro servers

This 512 GB kit contains eight 64 GB Registered ECC RDIMMs built to the DDR5-6400 (PC5-51200) standard at 1.1 V with CL52 timing. The 4Rx4 rank structure and 288-pin form factor match the memory controller expectations of the Supermicro X14SDW-64CM-SP9F motherboard so the system recognises the full capacity at rated speed.

Upgrade from smaller or slower DDR5 RDIMMs

Replacing lower-capacity DDR5 Registered modules or slower DDR5 speeds with this kit lets you populate every slot at the board's maximum validated frequency without mixing ranks or voltages. The jump is worth it when your workloads need the full 512 GB at DDR5-6400 and the motherboard population rules allow all eight slots to be filled with 4Rx4 modules.

Capacity headroom for dense virtualisation

Eight 64 GB modules deliver 512 GB total, giving ample room for large VM fleets, container clusters or analytics datasets that fit in DRAM. Headroom runs out when the application working set exceeds 512 GB or when the board's memory population rules restrict the number of 4Rx4 DIMMs per channel.
